Secured Loans
Replacing your windows can cost thousands of pounds. A secured loan lets you borrow against your home's equity to spread that cost, often with lower monthly costs than a personal loan.
A secured loan for windows lets you borrow money against the equity in your home to cover the cost of replacement windows, then repay it in monthly instalments over an agreed term. Because the loan is secured against your property, lenders can often offer larger amounts and more flexible terms than an unsecured personal loan.
A secured loan is a serious commitment, and your home is at risk if you don't keep up repayments, so it's worth comparing this option against personal loans, credit cards, and window company finance before deciding.
Replacing your windows is one of those jobs that's hard to put off once you've noticed the draughts, condensation, or rising energy bills. Double glazing for a typical 3-bed house costs between £4,000 and £8,000, so finding the right way to pay for it matters just as much as choosing the windows themselves. A secured loan for windows gives you a lump sum to cover the work without draining your savings or waiting years to save up.
Paying cash for new windows sounds ideal, but it isn't always practical. A full house of double glazing can cost more than many people have sitting in savings, and emptying your emergency fund for home improvements leaves you exposed if something else goes wrong. A loan lets you spread the cost of energy-efficient upgrades over manageable monthly payments instead.
These figures assume standard uPVC casement windows. Choosing timber frames, sash windows, or triple glazing can push costs 25-50% higher. Upgrading from single glazing to double or triple glazing can also improve your home's energy efficiency and help reduce heating costs.
There are good reasons to spread the cost of new windows rather than paying upfront:
If your current windows are only 10-15 years old but a specific pane has failed or a frame is damaged, ask about repair or partial replacement before committing to a full loan. It's often a fraction of the cost of replacing every window in the house.
Not all window financing options work the same way. The right choice depends on how much you're borrowing, your credit history, and whether you own your home. You could consider an unsecured personal loan, a 0% purchase credit card, a secured home improvement loan, window company finance, or adding the cost to your mortgage.
Personal loans don't require you to put up your home as security. They're quicker to arrange and don't put your property at risk if you can't pay. Typical borrowing ranges from £1,000 to £25,000 over terms of 1 to 7 years, with approval often possible within a few days.
Best for: smaller window projects, such as single rooms or partial replacement, borrowers with good credit scores, and those who don't want to secure debt against their home.
Drawbacks: higher costs than secured options, shorter terms mean higher monthly payments, and your credit score heavily affects what you're offered.
A secured loan uses your home as collateral, meaning your property acts as security for the loan. This is often the most cost-effective option for larger window projects, with borrowing available from £5,000 to £500,000 over terms of 3 to 30 years.
Best for: full house window replacement, borrowers who want lower monthly payments, those with less-than-perfect credit, and homeowners with good equity.
Drawbacks: your home is at risk if you don't keep up repayments, the approval process takes longer, and fees may apply.
Many double glazing companies offer their own finance deals, often advertised as "buy now, pay later" or interest-free credit, with interest-free periods of 6-24 months common.
Best for: those who can pay off the balance within the promotional period, and anyone who wants the convenience of arranging finance and windows together.
Drawbacks: you're limited to one supplier's products and prices, costs after the promotional period can be high, and it may not offer the best overall value once you factor in the window prices.
Credit cards can work for smaller window purchases, especially if you have access to a 0% purchase card with an introductory period of 12-24 months.
Best for: smaller purchases, those with access to 0% cards, and borrowers who can clear the balance within the interest-free period.
Drawbacks: credit limits may not cover the full project, costs after the promotional period can be high, and it can encourage overspending.
Adding to your mortgage can be a way to fund windows, but it isn't always the best option. It extends the debt over your full mortgage term, potentially 25 years or more, and may trigger early repayment charges on your existing mortgage.
Best for: those already planning to remortgage, or very large projects combined with other improvements.
Drawbacks: the complexity and cost of remortgaging may not be justified for windows alone, and it extends your repayment term significantly.
Not sure which option suits you
Tell us about your project and we'll compare secured loans, personal loans, and other options from a wide range of lenders to find what suits your circumstances.
For homeowners replacing all their windows, a secured loan often hits the sweet spot between affordability and total cost. Secured loans for replacement windows can come with flexible repayment terms, including periods of up to 10 years or more, so you can spread the cost in a way that suits your budget.
A longer term generally means lower monthly payments but more paid overall, while a shorter term costs less in total but pushes up the monthly cost. There's no single right answer here: it depends on what you can comfortably afford each month versus how much you want to pay overall. An advisor can talk you through the trade-offs for your circumstances.
The amount you can borrow with a secured loan depends primarily on two things: your home's equity and your ability to afford the repayments.
Equity is the portion of your home you own outright: your property's value minus what you owe on your mortgage.
Example: your home is worth £280,000 and you have £165,000 left on your mortgage. Your equity is £115,000.
Most secured loan lenders will let you borrow up to 85% of your equity, though some specialist lenders go higher. Using the example above, 85% of £115,000 is £97,750, far more than you'd need for windows.
Having equity available doesn't automatically mean you can borrow against it. Lenders must check that you can afford the monthly repayments alongside your existing commitments, including:
Most lenders want your total debt payments, including the new loan, to stay below 40-45% of your gross monthly income.
Sarah earns £3,400 a month. Her existing commitments are a £850 mortgage payment, £180 in car finance, and a £45 credit card minimum payment - a total of £1,075, or 32% of her income.
At 45% of income, her maximum total debt payments would be £1,530, leaving £455 available each month for a new secured loan payment. A lender would use that headroom, along with the term she chooses, to work out how much she could borrow, comfortably enough for window replacement with room for other improvements.
Secured loan rates vary significantly based on your circumstances. Understanding what influences your rate helps you assess whether now is the right time to borrow. Your borrowing history, including how you've managed previous loans and credit, can also affect the rate and terms you're offered.
Your credit history affects the rate you're offered, but it isn't the only factor. Generally, a stronger credit score, meaning fewer missed payments, lower existing debt, and a longer credit history, means access to more competitive rates. A weaker credit score doesn't rule you out, but it usually means a higher rate to reflect the extra risk to the lender.
The more equity you have relative to your borrowing, the lower your rate tends to be. Borrowing a smaller amount against a larger amount of equity (a lower LTV) typically gets better rates than borrowing a larger amount against the same equity (a higher LTV).
Smaller loans and shorter terms can sometimes attract slightly higher rates because they're less profitable for lenders. But longer terms mean paying more overall, so there's a trade-off between monthly affordability and total cost.
The wider interest rate environment, including changes to the Bank of England base rate, affects what lenders can offer at any given time. Because rates move, it's best to speak to an advisor for up-to-date figures rather than relying on published examples.
Understanding the total cost helps you make an informed decision. A loan for windows involves more than just the rate you're charged.
Secured loans typically involve several fees:
Not all lenders charge all these fees, and some offer fee-free products. An advisor will always explain the full costs before you proceed.
When you add up the interest and fees on a secured loan, the total cost of borrowing can look significant. It's worth weighing that against what you gain: if your old windows are single-glazed or draughty, replacing them can meaningfully cut your heating bills, reduce condensation, improve security, and support your home's value. For many homeowners, the ongoing energy savings offset a good part of the borrowing cost over the life of the loan. An advisor can help you compare the total cost of different options side by side.
A secured loan is a serious financial commitment. Before applying, make sure you understand what's involved. All borrowing is subject to approval and depends on your individual circumstances.
Your home may be repossessed if you do not keep up repayments on your mortgage or any other debt secured on it.
This is the most important thing to understand. If you don't keep up repayments on a secured loan, the lender can ultimately repossess your home to recover what you owe. Before taking one out, ask yourself:
If you want to pay off your secured loan early, perhaps because you sell your home or receive an inheritance, you may face early repayment charges. These typically range from 1-5% of the outstanding balance during any fixed-rate period. Always check the terms before committing, especially if you might sell your property within the loan term.
A secured loan counts towards your total debt when you apply for other credit. If you're planning to remortgage or need other borrowing in future, factor in how this loan affects your overall position.
Applying for a secured loan leaves a record on your credit file, and multiple applications in a short period can affect your score. Initial searches typically use a soft check that doesn't affect your credit, before moving to a full application with your chosen lender.

Applying for a secured loan takes longer than a personal loan, but the process is straightforward. You can start online or by phone, and an advisor will guide you through each stage.
How it works
Most applications complete within 2-4 weeks, from initial assessment to funds landing in your account.
Initial assessment
We'll discuss your circumstances, how much you need, and what you want to achieve. This helps identify which lenders are most likely to consider your situation. At this stage we run a soft credit check that doesn't affect your credit score.
Documentation gathering
You'll need to provide proof of income (payslips or tax returns if you're self-employed), recent bank statements, your mortgage statement, ID and proof of address, and details of existing debts. Getting these together promptly speeds up the process.
Full application
Once we've found suitable lenders, we submit your application. This triggers a full credit check, and the lender reviews your documentation and circumstances.
Property valuation
The lender arranges a valuation of your property to confirm the equity available and that it's suitable security. You don't usually need to be present.
Offer and completion
If approved, you'll receive a formal offer setting out the loan terms. There's a reflection period before you accept. Once accepted and the legal work completes, funds are released to your account.
A secured loan isn't the only option. Depending on your circumstances, one of these alternatives might suit you better.
Other options
Energy efficiency grants
Some homeowners qualify for help with energy efficiency improvements, including windows. The ECO4 scheme can cover a significant portion of double glazing costs for low-income households or those receiving certain benefits, and eligibility often depends on your property's EPC rating. Home Energy Scotland offers interest-free loans up to £15,000 for energy efficiency improvements, and some local authorities offer their own grants, so it's worth checking with yours.
Savings and waiting
If your existing windows are adequate, just not ideal, saving up over 12-18 months might be realistic. Weigh up whether the energy savings and comfort improvement justify borrowing now versus waiting.
Partial replacement
You don't have to replace every window at once. Prioritising the worst-performing windows, often north-facing rooms or large patio doors, gives the biggest improvement for a lower cost.
Secondary glazing
For listed buildings or anyone wanting a lower-cost option, secondary glazing (adding a second layer inside your existing windows) costs significantly less than full replacement, typically £100-£300 per window installed.

Why choose us
Common questions
There's no such thing as a dedicated "window loan" - you'd use a personal loan, secured loan, or another form of borrowing. The good news is that most lenders don't restrict what you use the funds for, so you're free to spend it on windows.
With a secured loan, you can typically borrow from £5,000 to £500,000, depending on your equity and affordability. Most window replacement projects fall between £4,000 and £15,000, well within typical secured loan ranges.
It depends on your circumstances. If paying cash would empty your savings or mean waiting years to afford the work, financing can make sense. The key is making sure you can comfortably afford the monthly payments alongside your other commitments.
Secured loans are often more accessible than personal loans if your credit isn't perfect, because your home provides the security. We work with specialist lenders who consider circumstances that mainstream banks won't. Rates will usually be higher, but approval is often still possible.
Typically 2-4 weeks from application to receiving funds. Having your documents ready and responding promptly to requests can speed things up.
Yes, but check for early repayment charges first. These typically apply during any fixed-rate period and can be 1-5% of the outstanding balance.
No. The lender arranges and pays for a valuation as part of the application process, so you don't need to arrange your own surveyor.
You'll need to repay the secured loan from the sale proceeds, along with any early repayment charges. The loan is a charge on your property, so it has to be cleared when you sell.
Yes, that's a common approach. If you're planning other home improvements, combining them into one loan means one application, one set of fees, and one monthly payment.
Lenders don't usually restrict what you use the funds for, but they may ask about your plans. Being clear that it's for home improvements is perfectly acceptable.
Arranging your own finance often gives better value. Window company finance may seem convenient, but you can lose negotiating power on the window price, and rates after any promotional period can be high. It's worth comparing the total cost of both options.
A secured loan sits as a second charge behind your mortgage, while remortgaging replaces your existing mortgage with a new, larger one. Remortgaging might offer a lower rate, since first-charge mortgages are typically cheaper than second-charge borrowing. But remortgaging may trigger an early repayment charge on your current mortgage, and the new rate would apply to your entire borrowing, not just the new amount. A secured loan keeps your mortgage separate, which can be an advantage if you have a good mortgage rate locked in.
Subtract your outstanding mortgage from your property's current value - that's your equity. You can check your property's approximate value on sites such as Zoopla or Rightmove. For a secured loan, most lenders need your total borrowing (mortgage plus new loan) to stay below 80-85% of the property value.
Both options exist. Fixed rates stay the same for a set period, typically 2-10 years, then usually switch to a variable rate. Variable rates move with market conditions, typically tracking the Bank of England base rate. Fixed rates provide certainty; variable rates offer potential savings if rates fall.
There's no single minimum credit score that applies across all lenders. Mainstream lenders typically look for a solid credit history, while specialist lenders on our panel consider applications from people with past defaults or other credit issues. Your credit profile affects the rate you're likely to be offered as well as which lenders will consider your application.
